The following fields are maintained in the POS Prompt parameter. 

The values are used by POS to present the message and configure how it is to be displayed in POS. 

The Test button on the properties page allows the message to be seen as it will be displayed in POS.

The tool bar on the POS Prompt Message property page has two tool bar options to define a query for Customers and Products. 

These rules are similar to the sale promotions and auto discount rules.  

Each rule parameter allows an advanced query to be created based on the respective item, Customer or Product. POS will then use these rules to trigger a prompt message. 

See the section below that describes how POS uses the rules.

Each rule form, Customer or Product, has a priority setting that sets a priority value for the Prompt Message. 

This is a user defined number used by POS to prioritize the rules into a known order.  

The priority setting can be different between the Customer and Product rules. 

How POS Uses the Prompt rules

When POS starts, a list of Customer rules and a list of Product rules are created for the POS session. 

These lists are not refreshed until POS is restarted. Messages coded as deleted or to “Never Display” are not included in the lists. 

Each set of rules, Customer and Product, are then organized into the following order for searching:

1. The priority setting for the prompt message.
2. The Prompt Message Code.
3. Each of the queries in rule properties in the order shown on the form.

When applying a rule, POS will search each rule in the above order and use the first rule that matches. 

Once a rule is found, [i]merchant does not search for another matching rule.

Customer Prompt rules

The customer prompt rules will be reviewed each time a customer lookup is done in POS. 

Recalling a sale or reselling a voided sale will not activate the customer rules.

***Note***: Customer prompt rules are not restricted to messages. A product or service can be assigned to a customer rule.

Product Prompt rules

The Product Prompt rules are evaluated as each product it brought into the sale.

[i]merchant will first check to see if the product has a rule explicitly coded in the POS Prompt field of the product item. I

f so this is the rule that will be used. If the product does not have a rule, the product prompt rules are evaluated. 

Similar to Customer, a recalled sale does not evaluate the rules.

If a customer or product rule offers another product and the product offer is accepted, the new product's rules are evaluated.
